Currently dating her Wanderlust costar Justin Theroux, 40, Aniston adds: "I still kind of go with, if it happens, it happens. I'm calm and peaceful with whatever the plan is. It's not something where I'm going, 'I gotta have a kid!'"

Aniston tells GQ she's not looking for a "picture-perfect life," either. "I think that's sort of cliche, isn't it? Like, if you want to be happy, you should have the house, the husband, the kids… Kids are messy!"

Rudd chimes in: "Having two, I can verify this."

Aniston — who joked that "Sarah JessicaParker actually birthed one" of her alleged children — eventually gets tired of addressing pregnancy rumors, saying: "I'm drawing the line on the children conversation. You heard it here. I'm not knocked up know."

The Friends alum does, however, feel more comfortable discussing the pros and cons of marriage.

"It's a growing, literally living thing. There's going to be growing pains, there's going to be awkward moments — your lanky phase, your pimpled phase. I think that's the beauty of a relationship," says the actress, once married to Brad Pitt, 48. "But if the road starts to [diverge] and one person is growing this way and the other is growing that way… Sometimes that can happen and you can stay together, and sometimes you can't."
